Great!  This means that this fix solved the problem.  You have now run
into another, known one: the "core" library is badly out of date, and
needs to be updated to work with newer releases of bin-prot.  We will
make a release within (probably) the next few weeks.  In the meanwhile
you might want to downgrade bin-prot to make it work with "core".

I'll add a patch to bin-prot to make it work on Macs in the meanwhile...

Regards,
Markus
